NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 17, 1912.

To all whom it may concern:

Be it known that I, WALTER A. STATT- MANN, citizen of the United States, resid- Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide a simple and efficient non-refillable bottle stopper, and consists in the features of construction and combinations of parts hereinafter fully described and particularly claimed.

In the accompanying drawings illustrating the invention: Figure lis a fragmentary central longitudinal section of the neck portion of a bottle equipped with a bottle stopper embodying my invention, the latter being shown in elevation. Fig. -2- is a view similar to Fig. -1- showing the bottle in tilted position for discharge of the contents and showing the stopper in central longitudinal section. Fig. -3 is a detail horizontal section on the line 38 of Fig. 1. Fig. 4 is a detail central longitudinal section showing the stopper as positioned in Fig. -1.

My invention has for its particular ob ject to provide a bottle stopper, adapted to prevent refilling of a bottle equipped therewith, which is extremely cheap, simple and eflicient, and which is so constructed and arranged that the valve employed will automatically close before the bottle returns to horizontal position after having been tilted to a greater angle for discharging the contents thereof.

The invention consists particularly in the means provided for effecting a tilting move ment of the valve and for throwing the center of gravity thereof inwardly of the bottle or of the valve seat whereby closure of the valve when the bottle attains a given position will 'be assured.

The neck A of the bottle is provided contiguous to its juncture with the body B thereof with an annular shoulder C upon which the lower end portion of the sleeve or housing D for the valve seat and valve is adapted to rest, said bottle neck having an annular contracted portion E disposed above and contiguous to said annular shoulder G in which the small cork ring F is adapted to be received and engaged for effecting a fluid-tight joint around the housing D and preventing withdrawal of the latter from the bottle neck.

The housing D is substantially cylindrical, the lower end portion thereof being annularly enlarged and slightly tapered, as at G, and said annular contracted portion E of the bottle neck being similarly slightly tapered for purposes which will be hereinafter fully set forth. Said housing D is open at its upper end and is covered at said end by a cap H below which and above the upper end of the housing D is a plurality of openings I for the passage of liquid from the bottle. The said cap H is supported upon small relativelydelicate standards J which are readily severed by strains on said cap H imposed for purposes of removing the housing from the bottle neck. The said standardsJ may be secured in any suitable manner'to the housing D and cap H, as will .be obvious, but in the instance shown they are illustrated as being integral with both the said parts. 1

By tapering the portion E of the bottle neck so as to slight-1y contract the upper end portion thereof, considerable pressure is required to force the cork ring F into the same and, likewise, greater force will be required to effect withdrawal of the housing D.

Disposed in the lower end of the housing is a valve seat K consisting of a flat plate provided with a relatively large central opening L. The said plate K is provided with a narrow annular flange M, the free edge of which terminates in a plurality of projections N which are bent so that they converge toward each other at their free ends at an angle of about sixty degrees more or less to the plane of said plate K. The free space bordered by the free ends of said projections M affords an opening of considerably less diameter than the opening L in said plate K and also of considerably less diameter than the disk valve 0 seating on said plate K around said opening L. The said plate 0 is a flat circular metal plate provided with a small. annular flange P which is adapted to seat on said plate K. The depth of said flange P added to the thickness of the plate O is substantially equal to the depth of the annular flange M of the plate K. Secured to the center of said plate 0 is a stem Q terminating in a weight R at its free end, said stem Q being relatively heavy and said weight R likewise very heavy compared to the weight of said plate 0 and is adapted to project through the opening L into the body B of the bottle. The length of the stem Q and weight B may be changed and varied as well as the weight thereof to throw the center of gravity of the valve O as far inwardly from the valve seat as may be desired. The diameter of said valve 0 is greater than the diameter of the opening L and less than the diameter of the plate K and is substantially equal to the diametric distance between a point in the'flange M of the plate K to the diametrically opposite point in the periphery of the wall of the opening L, said valve 0 being thus capable of limited lateral movement on its seat in all direct-ions without afi ord- I ing an opening for the passage of liquid.

The operation of the device is as follows: The valve stem Q with its weighted end serves to maintain the valve 0 normally on its seat. In tilting the bottle the valve primarily moves laterally of its seat until the periphery of said valve 0 rests upon the lowest point in the inner face of the flange M. As the tilting movement is continued until the bottle is substantially inverted or tilted to an angle throwing the neck thereof lower than the body the valve will open by turning on that point in its periphery engaged with the flange M as a fulcrum and tilt to a position in which the diametrically opposite point in its periphery engages the projections N which limit the opening movement thereof. Liquid may now flow from the bottle relatively freely owing to the relatively large opening thus provided, this being essential to the success commercially of the device and constituting an object of the invention. As soon as the desired quantity of liquid has been discharged from the bottle the same is returnedto its upright position but in so returning the same the weight Q and valve stem R will cause the valve to again turn on its fulcrum into closed position before the bottle has attained a horizontal position so that a refilling of the same is rendered substantially impossible. By rendering the depth of the plate or valve 0 with its flange P substantially equal to the depth of the flangeM a longitudinal movement of the fulcrum edge of the valve relatively to its seat is prevented'so that immediately upon the closing movement of the valve taking place the same will obviously effect a hermetically sealed joint on its seat. The valve seat K is inserted into the lower tapered end of said housing D and the lower edge of the same then crimped inwardly thus securing said valve in place therein.
